Plastic Centrifugal Fans

We do not offer single-phase motors for our plastic fans. This is for the following reasons:

• Single-phase motors must operate above 75% of full load current to limit the excess power dissipating as heat. This heat causes the motor to burn out.  
• Because the design and actual duties achieved following installation are seldom the same, we use our experience in air movement to mitigate any potential problems by sizing fan motors at the top end of their capability. We base our calculations on the fan duty specified by the client.
• Short intermittent use of a single-phase motor may be acceptable as the heat rise within the motor would be limited, and the unit would cool down between periods of use. However, we do not recommend or supply this type of motor for any fan applications.

Should a single-phase motor still be requested, we would require this to be free-issued for us to fit. We would be unable to provide a warranty on the fan unit due to the potential issues that may be experienced.

APMG will always recommend three-phase motors controlled using a single-phase input/three-phase output inverter.

The E-Series Plastic Centrifugal Fans by APMG Plastics is designed to serve a range of applications. 

1. Fume Cupboards/Extract Systems: One of the primary uses of the centrifugal fans are in fume cupboards (also known as fume hoods). These are ventilated enclosures where hazardous materials, especially chemicals, can be handled safely. The fan ensures that toxic fumes, vapours, and dust are efficiently extracted and expelled, maintaining a safe user environment.
2. General-Purpose Ventilation: The E-Series versatile designs make each option suitable for various general ventilation needs, ensuring optimal airflow and mitigating the build-up of harmful substances in various settings.
3. Chemical Resistance Applications: Given the fan’s manufacturing from chemical-resistant thermoplastic materials and the mitigation of 95% of its steelwork, it is especially suited for environments exposed to corrosive chemicals. This makes the fan ideal for industries such as chemical processing, laboratories, and other areas with frequent chemical exposure.
4. Indoor and Outdoor Locations: The E-Series fan’s ability to cater to both L90° and R90° discharges and its design makes it an ideal choice for internal and external settings. This includes places that require vertical discharge ducts.
5. Temperature Control: In environments where maintaining a specific temperature is crucial, these fans can help circulate the air, especially since they have a recommended maximum operating temperature of 40°C.
6. Specialised Applications: Given its customisable features, such as optional inverter drives, fabricated non-return dampers, and a range of PVC or polypropylene vent tubes and fittings, the E-Series can be tailored to fit specialised industrial applications as required by the user.

The E-Series fans by APMG Plastics use materials designed for durability, efficiency, and chemical resistance.

1. Thermoplastic Materials: The fan is manufactured from chemical-resistant thermoplastic materials, ensuring durability and resistance against various chemicals.
2. uPVC (Unplasticised Polyvinyl Chloride): The fan casing is made from uPVC, known for its rigidity, strength, and resistance to chemicals and corrosion.
3. Integra-flex PVC: The fan features clear ‘Integra-flex’ PVC inlet and outlet duct connections. This not only enhances its chemical resistance but also ensures ease of installation.
4. Polypropylene: The forward curved multi-vane moulded fan impeller is manufactured from polypropylene, a durable plastic known for its chemical resistance, lightweight properties, and fatigue resistance.
5. GRP (Glass Reinforced Plastic) Pultrusion: The fan’s mounting rails are made of GRP pultrusion, providing strength, durability, and resistance to various environmental conditions.
6. Rubber: The fan includes four off-rubber anti-vibration mounts to reduce vibrations and ensure smooth operations.
7. Steel: While 95% of the steelwork in the fan’s construction has been mitigated to offer greater chemical and corrosion resistance, some components may still incorporate steel. 
8. Stainless Steel: The fixings used in the fan are made of stainless steel, which is renowned for its corrosion resistance, strength, and longevity.

The available sizes for the E-Series fans are based on the fan’s diameter. The standard sizes available are:

1. Ø160
2. Ø200
3. Ø250
4. Ø315

These sizes are in millimetres (mm) and refer to the fan’s diameter. Depending on the specific requirements of an application, customers can choose from these sizes to get the best fit for their needs.

The E-Series plastic centrifugal fans will simplify maintenance procedures in the following ways;

1. Easy Access to Impeller and Motor Assembly: The backplate design allows the impeller and motor assembly to be removed from the unit without disconnecting the fan from the ductwork system. This means that maintenance personnel can access and service these critical components without dismantling the entire fan or disrupting the connected ducts.
2. Reduced Downtime: Since the impeller and motor assembly can be removed without disconnection from the ductwork system, the downtime required for maintenance is minimised. This ensures that operations can resume quickly after maintenance, reducing interruptions and potential financial impacts.
3. Integra-flex Inlet and Outlet Connections: The fan has clear ‘Integra-flex’ PVC and outlet duct connections. These connections simplify installation and maintenance procedures as they can be easily detached and reattached.
4. Forward Curved Moulded Impeller: Using a moulded impeller made of polypropylene ensures durability and less wear and tear, reducing the frequency of maintenance required.
5. Direct Drive Arrangement: Being a directly driven fan unit, the E-Series fan eliminates the need for belts typically found in belt-driven fans. This means fewer components to maintain and replace over time.

The following motor options are available for the E-series range;

Motor Efficiency:

• • Motors are IE1 or IE2 efficient as standard, depending on the speed rating.
  • IE3 efficient motors are available on request. This indicates that customers can choose motors based on their efficiency requirements, with IE3 being a higher efficiency standard than IE1 and IE2.

Motor Enclosure:

• • The standard motor has a minimum IP55 enclosure, protecting against dust and water. This makes it suitable for various environments where these factors might be a concern.
  • The enclosure can be tailored if a customer needs a higher protection level.

Motor Drive:

• • The fan features a directly driven unit, meaning the motor drives the fan directly without belts or other intermediary mechanisms. This can result in less maintenance and more efficient power transfer.

Motor Frame Size:

• Different fan models within the E-Series have different motor frame sizes, as the datasheets show. For instance:             
  • • AP160E has motor frame sizes 80, 90, and 100 mm
    • AP315E has motor frame sizes 80, 90, and 100 mm
    • AP250E has motor frame sizes 71, 80, 90, 100, and 112 mm
    • AP200E has motor frame sizes: 71, 80, 90 mm

Yes, optional extras are available for the E-Series range. These include the following;

Inverter Control:

• • 1ph to 3ph: The inverter can convert single-phase power input to three-phase output. It can be helpful in settings where only single-phase power is available, but a three-phase motor is used.
  • 3ph to 3ph: This inverter takes in three-phase power and outputs it in a modified form, typically to control the speed and torque of the three-phase motors.

Fabricated Non-return Dampers: These devices only allow air to flow in one direction. They help maintain consistent airflow and pressure in ventilation or extraction systems by preventing backflow.

Vent Tube and Fittings:

• • A range of PVC or polypropylene vent tubes and fittings. These materials are known for their durability and resistance to chemical corrosion, making them suitable for various applications.

The recommended maximum operating temperature for the E-Series fan is 40°C. It’s essential to adhere to this recommended temperature to ensure the fan’s optimal performance and longevity. Operating beyond this temperature may lead to decreased efficiency, increased wear and tear, or potential damage to the fan components, especially given the plastic materials used in its construction.

The main differences between the E-Series fans, such as the AP160E, AP315E, AP250E, and AP200E, lie in their dimensions and airflow capacities. While all these fans share similar features, such as chemical-resistant materials, ease of maintenance, and standard sizes, their specific dimensions and capacities vary to cater to different application requirements.
